Loutro Beach is not really suitable for swimming. There is a caique repair yard in the bay and the beach is covered with uncomfortable big stones. Also there are a lot of plants in the water. You could go in for a swim, but why bother since there are so many other great beaches on the island.
Only by foot or by boat: these are the only ways to reach the beach of Pezoulia. If you chose the second, you’d better prefer the left side (from your perspective) of the bay, not only to enjoy the beach but also to take the way that will lead you to Aloni; it’s a large plateau with a huge fig and a sealed well.
Parianos beach is set on the south west coast of Koufonissia and it consists in a large sandy beach naturally protected from the winds as it is in fact the harbor where the small fishing boats are anchored. This place is ideal for families with young children and people who do not like transportations.
On your quest for good beaches in Koufonisia, you can go from Platia Pounda to Pori and continue to a small beach called Gala. Gala means milk in the Greek Language and the beach gets this distinctive name from the frothy waves that one can see in the interior of the caves.
Just 200-300 meters separate the headlamps from the shores of the Italian or otherwise Platia Punta. The trail moves along the coast and goes side by 2-3 small individual 'pools' with pebbles or sand, fringed by rocks, which they prefer mainly nudist.
